RESTful service fails POST query, why?

Question

JavaScript

Hello,
I am new to RESTful services. I'll try to describe the problem I'm facing. I have some external RESTful service to which I connect and collect data using GET requests.
But now I came across a request that essentially returns data, but why does it work via POST.

Tried to recreate it in POSTMAN but nothing worked.
First, I gave the status 415 Unsupported Media Type , searching the Internet, found that the problem was in the content format, set it to the same one that I found in the Inspector(Network). Then I added all Headers as in Inspector(Network).
After all these manipulations, it gives the status 500 Internal Server Error. I don’t understand why it gives this status when the same request with the same settings passes as status 200 on the site.
I don’t know which way to dig, maybe someone has an idea what to do next or how to solve this problem.
Thanks,
Dmitry

Post requests usually also have a body, take a closer look at the information about the request.
